Ferris wheels

[Danae02]

The height of a carriage on a ferris wheel is given by:
h = 12-11cos(pie/30 t) where t is the time in seconds. The time for the ferris wheel to complete one revolution is: ...
How can i work this out? :?

Where is it at t=0?

h = 12-11cos([pi/30]*0) = 12-11*cos(0) = 12-11 = 1

When does it get back there?

[pi/30]*t = 2*[pi] ==> t = 60
